System Leak Test
The temperature compensated leakage test can be used to check the leak
tightness of systems. For this purpose both the system pressure and the
ambient temperature are measured over a defined period of time.
To this end, a temperature probe may be connected to measure the
ambient temperature (recommendation: Deactivate the surface
compensation factor and use an NTC air probe or Bluetooth
temperature Smart Probes) or Smart Probe for air temperature
measurement. This provides information about the temperature-
compensated differential pressure and the temperature at the
beginning/end of the test. Due to the temperature compensation, the
actual pressure drop is displayed as delta P. If no temperature probe is
